Police in San Pedro were investigating a possible gang- related shooting of a 34-year- old man, who was hospitalized early Sunday with upper-body wounds.

The man, whose name was withheld, was shot with a shotgun, police said.

Officers responded to Providence Little Company of Mary Medical Center San Pedro at about 12:15 a.m. to interview the victim, but he did not want to cooperate, said Los Angeles Police Sgt. Danny Contreras.

The shooting occurred at Mesa and 17 th Streets, and the victim suffered several pellet wounds to the upper body, he said.
